Key specifications
 Sensor type: DS18B20 digital temperature probe
 Connection: wired interface for direct connection to compatible controllers
 Measurement range: designed for ambient temperature measurement (refer to manufacturer's DS18B20 probe range)
 Probe form factor: compact sealed probe suitable for indoor and sheltered outdoor use
 Typical applications: HVAC, environmental monitoring, aquariums, greenhouses, smart home systems
How to use
Connect the wired probe to a compatible Sonoff controller or monitoring device following the controller's wiring diagram and power requirements. After connection, configure the controller or software to recognize the DS18B20 sensor type and set desired reporting intervals. Position the probe in the location where representative ambient temperature readings are needed, avoiding direct sunlight or heat sources for accurate measurement. Verify readings in the controller interface and use calibration features if available to align measurements with a reference thermometer.
Usage recommendations
For reliable long-term operation, route the cable to avoid mechanical strain and protect the probe from prolonged direct exposure to water or extreme weather unless the installation location and probe sealing are suitable. Use short reporting intervals for applications requiring timely alerts and longer intervals to conserve network and controller resources when continuous monitoring is not critical.
